Abstract

Because of the environmental modifications made by anthropic actions, the ecological systems have been losing their organisms, resulting in simplification of trophic interactions, which bring out species instability, especially at agricultural and forest systems. Thus, to understand the performance of natural enemies it is primordial to their usage at integrated pest management programs. In this study, the predator prey interactions of two species from the suborder Heteroptera, Podisus nigrispinus and Graptocleptes bicolorwere investigated, to understand their dynamics and functional responses, with some preys from the Lepidoptera order.
